Methods and arrangement relating to a radio communication network

摘要

The present invention is related to a terrestrial cellular radio communication network comprising at least a first base station (BS1) in which a common set of multi carrier power amplifiers (409-412) are used to amplify radio signals transmitted by the first base station (BS1) in different cells. The invention enables reductions in the total maximum output power the first base station (BS1) needs to support when downlink power control functions, such as power control or discontinuous transmission, and/or Adaptive Channel Allocation are applied in the cells served by the first base station (BS1).
